Extended rod of slide mechanism for drawer slide track

ABSTRACT

An extended rod of slide mechanism for drawer slide track comprises a control stop mounted on the extended rod and a stop stock mounted on the front of the slide track wherein the control stop is an integrally formed extrusion with a swing block fixed on the extended rod by a rivet. The swing block has a cut section at one end to stop the stop stock of the slide track. The extended front end of the swing block forms a push-pull section. Pushing or pulling the push-pull section will free the cut section from the stock causing the extended rod disengages the slide track and pull the drawer out of the slide track. Regardless whether the slide mechanism is installed on the right side or the left side of the drawer, it provides a disengaging direction, easy the operator to take the drawer out of the slide track.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the major components of the slide mechanism ofthe drawer, particularly the control stop operated to disengage and stopthe extended rod from the slide track for the multiple drawer slidetracks.

2. Description of the Related Art

For the structure of multiple drawer slide tracks, when drawer is pulledout and the extended rod travels to the end of the slide track, thereprovides a stop mechanism on the join of the slide track and extendedrod to control the stop operation, and prevents the extended rod fallingoff from the slide track. This stop mechanism consists of one controlstop mounted at the end of the extended rod and a stop stock mounted onthe slide track. If it is intended to disengage the extended rod fromthe slide track, use the stopping operation by the control stop and stopstock of the stop mechanism, the extended rod can be released from slidetrack smoothly.

As shown in FIGS. 1 through 4, it is the control stop 11′ of the priorart where the control stop 11′ is locked on the extended rod 1′ by arivet 3′. The control stop 11′ has a guide section 111′ and a swing rodsection 112′ extended at the rear side. The swing rod section 112′ has acut section 113′ at the bottom of the front end, when the extended rod1′ is installed on the slide track 2′, the stop stock 21′ and cutsection 113′ will prevent the extended rod 1′ from disengaging the slidetrack 2.

The slide track is generally installed on both sides of the drawer. Ifit is intended to disengage the extended rod 1′ from the slide track 2,on the left side of the drawer, it is necessary to swing downward theswing rod section 112′ of the control stop 11′, so the cut section 113′moves downward as shown in FIG. 3, the left side extended rod 1′ isfreed from the stop stock 21′ of the slide track 2′ and can be pulledout the slide track 2′. For the control stop 11′ of the right sideextended rod 1′ is necessary to swing upward by the swing rod section112′ to control the cut section 113′ swing upward as shown in FIG. 4,the right side extended rod 1′ is free released from the stop stock 21′of slide track 2′, This practice of disengaging the extended rod 1′ fromthe slide track 2′ differing the control stop 11′ of the extended rod 1′in left and right sides which renders too much inconvenience on thedisassembly. It requires prompt improvement.

In order to accomplish a uniform practice, a new control stop of slidemechanism was invented as shown in FIG. 5, the U.S. Pat. No. 5,169,238in which the extended rod 1′ has a stop section 4′ with a V slot 41 andan independent pull board 5′ comprised a control stop. When theextension section 51 ′ of the pull board 5′ is pushed into the V slot41′, both sides of the stop sections 42′ on the slot 41′ of the stopsection 4′ are forced to expand outward respectively to engage the stopstocks 21′ on the slide track 2′, so the extended rod 1′ is stoppedthereof. If the pull board 5′ is pull outward, the extension section 51′will leave the V slot 41, the stop sections 42′ of the stop section 4′will shrink inward and the stop stock 21′ of the slide track 2′ is freefrom both sides of the stop sections 42′ of the stop sections 4′, theextended rod 1′ is released from the slide track 2. However, even thoughthe stop section 4′ is separated from the pull board 5, the differentswing direction still exists on the left and right side of the drawer.For the production alone, the cost is high and the assembly is timeconsuming, not good for competition.

Due to the fact that the demand for the extended rod of the slidemechanism for the multiple drawer slide tracks is ever increasing andthe inconvenience caused by the upswing and downswing in disengaging thecontrol stop of the slide mechanism of prior art, a great efforts havedevoted to the improvement and now come up an improved control stopstructure of the slide mechanism.

SUMMARY OF THE INVENTION

The unique technology applied in this invention is that the control stopis an integrally formed extrusion with a swing section riveted on theextended rod. One end of the swing section extends to form a cut sectionfor engaging the stop stock of the slide track and the other end extendsto form a push-pull board. When the push-pull board is pushed or pulled,the swing section will pivot upward to disengage the cut section fromthe stop stock, permitting the extended rod to fall off the slide track.This improved control stop of the slide mechanism, regardless whetherbeing mounted on the left or right side of the drawer, is veryconvenient for the operation to disassemble the drawer. In addition, itis easy to fabricate and assemble, great beneficiary to themanufacturers. This is the main object of this invention.

DETAILED DESCRIPTION OF THE INVENTION

Please refer to FIG. 6, the control stop of the extended rod mainlycomprises a control stop 11 mounted on the extended rod I and the stopstock 21 mounted on the front end of the slide track 2.

As shown in FIGS. 7 through 10, the control stop 11 is an integrallyformed extrusion with a swing section 111 riveted on the extended rod 1.One end of the swing section 111 forms a cut section 112 for engagingthe stop stock 21 of the slide track 2. The other end of he swing 111forms a push-pull board 113 which starts from the fine bent and extendsoutward to become a broad board.

As shown in FIG. 11, when the push-pull board 113 is pushed, the swingsection 111 will swing up to disengage the cut section 112 from the stopsection 211 of the stock 21 and let go the extended rod 1 off the slidetrack 2.

As shown in FIG. 12, a part of the push-pull board 113 can extenddownward through the join of swing section which become a broad board,and mounted a right angle slant 114, here the push-pull board 113 worksas a pull board as shown in FIG. 13. Once the push-pull board 113 ispulled, the slant 114 will press on the swing section 111 and force theswing section 111 to make a turning action in the manner that the cutsection acts 112 as a leverage to disengage the stop section 211 of thestop stock 21, letting go the extended rod 1 off the slide track 2.

It is well learned from the above statement that the improved controlstop structure of he slide mechanism where it requires only pushing orpulling the control stop 11 to disengage the extended rod 1 from theslide track 2. It offers a convenience for the operation to disassembleand easy for the manufacturer to fabricate, gaining huge benefit andprogressiveness.
